L’anticorps anti-alpha 2 Macroglobulin Monoclonal Souris est utilisé pour la détection de alpha 2 Macroglobulin dans des échantillons de Humain. Il a été validé pour IHC (p).
I±-2-Macroglobulin (i±-2M) is a homotetrameric serum protein consisting of four identical subunits that form dimers through disulfide bonds. Initially, i±-2M was characterized as a pan-proteinase inhibitor that was able to bait proteinases into cleaving specific peptide sequences on i±-2M. This interaction induces a conformational change in i±-2M, thus enabling it to trap the proteinase and further inhibit its activity. Subsequently, i±-2M has been shown to function as a carrier protein and regulator of cytokines during inflammation. Circulating transforming growth factor i² (TGFi²) in serum is primarily bound to i±-2M, which renders TGFi² inactive. i±-2M also binds to IL-6 and, thereby, increases the concentration of IL-6 near lymphocytes, hepatocytes and stem cells involved in mediating the inflammatory cascade. Mutations and deletions in the gene encoding i±-2M are associated with an increased incidence of Alzheimer s disease (AD), which is consistent with the role of i±-2M in mediating the clearance and degradation of A i², the major component of i²-Amyloid deposits accumulated during AD.
